What Types of Management Systems are Required? • Data management • Ability to access multiple types of storage systems, across separate administration domains • Information management • Ability to migrate collection onto new information repository • Knowledge management • Rule-based ontology mapping • Characterization of rules under which collection is formed • Management of knowledge bases - Topic Maps
Information Management Hierarchy • Persistent Archives • Storage of information model, data model, along with data • Data Grid • Access to data in a different administration domain • Digital Library - Presentation / Information Discovery • Interlib - ADEPT, UC Berkeley Digital Library • Data Collection • Extensible Meta-data catalog - EMCAT • Data handling • SDSC Storage Resource Broker - SRB • Archival Storage • High performance storage system - HPSS
Digital Library Data Management • Persistent identifiers • Ability to move a data set without the name changing • Data set replicas • Management of multiple copies of a data set • Archival backup of data sets • Integration of disk data caches with archival storage • Persistent archives • Management of a collection through multiple cycles of technology evolution

Common Information Model • eXtensible Markup Language (XML) • Use tags to define semantic context for components of the data set • Document Type Definition (DTD) • Provides semi-structured representation for organizing tags that can be applied to groups of digital objects • Development of standards for tags • Digital sky, Protein Data Bank, Neuroscience brain images • California Digital Library - Art Museum Image Consortium
Applications • Support for distributed data collections • Federation of data collections to form digital library • Integration of digital libraries with archives • Finding aids for federation of digital libraries through mediation of information • Data grids for data access • Persistent archives
